Catering for Dietary and Allergen Needs

Dietary and allergen catering has moved well beyond "tick a box for vegetarian" over the last decade, and it's worth planning properly rather than treating it as an RSVP afterthought - both because it genuinely matters to affected guests and because UK caterers now take allergen handling seriously as a legal and safety matter, not just a courtesy.

Collect specifics, not just categories, on your RSVP. "Any dietary requirements?" with a blank line gets you more useful information than a checklist of pre-set categories, because it captures genuine allergies (which need careful handling) separately from preferences (which don't carry the same risk) - and it catches less common needs a fixed checklist would miss entirely. See invitation wording and etiquette for where this fits in your RSVP wording.

Pass genuine allergy information to your caterer directly and explicitly, not just as raw RSVP data. UK food businesses are legally required to declare the fourteen major allergens recognised in UK law when they're used as ingredients, and good practice around actually managing cross-contamination goes further still - a good wedding caterer will ask you for this information proactively - if they don't, raise it yourself. This is different in kind from a preference like "not keen on seafood," and it's worth flagging that difference to your caterer clearly so allergy meals get the additional care they need.

Don't let dietary catering become an obviously separate, lesser meal. The most common complaint I hear from guests with dietary needs isn't that they were catered for, but that the alternative meal was visibly an afterthought - a plain salad next to everyone else's plated dish. A good caterer can make a dietary alternative feel like a genuine part of the menu rather than a substitution, and it's worth asking to see or taste it in advance at your tasting, not just take it on trust. See the wedding breakfast, explained for how tastings and menu planning generally work.

On plus-ones and late dietary information: build a small buffer into your final catering numbers where possible, since dietary needs sometimes surface later than the main RSVP deadline - a guest who forgot to mention a need, or a late-added plus-one. Flag this possibility to your caterer early so it's a manageable adjustment rather than a last-minute scramble.

What I'd actually do: treat allergy information as safety-critical data that gets handed to your caterer directly and confirmed back by them, not just noted on a spreadsheet you assume they'll see - a caterer who confirms they've received and understood specific allergy needs is one you can trust to actually act on them.
